A post about Erecta Rack, right full of numbers:
600 lineal feet of 5″ beadboard taking up 36 square feet of floor. This is the first time we have taken the system up to 16 modules. Do you know how efficiently you can spray and rack in the shop or onsite and not end up with a hornswaggle? I do.
Weight bearing capacity of this system is rated for 500lbs at 10 levels, 250lbs at 15 levels. This is based on a 2 column support system, as shown in the picture to the right. On a 3 column support system (third set supporting the board centers), ratings increase by 33%. Good odds.
